6月4日，汉南长江大桥北岸锚碇沉井施工现场，80多名工人正在进行锚碇沉井下沉作 业，重达数百吨的预制钢筋部品通过巨型吊机，如积木般精准嵌入深达43米的沉井内。 建设中的汉南长江大桥 "这是世界公路工程第一大沉井，面积相当于14个篮球场，有15层楼高。"武汉交投汉南 桥项目公司工程部部长胡志红说，汉南长江大桥锚碇采用整体式沉井基础，面积近6000平方 米，首次下沉锚碇重约9.4万吨，沉井采用接高与下沉交替进行，目前已下沉深度5米。 编辑：李智恒 胡志红介绍，为抢抓主汛期来临前黄金建设期，工程日夜施工，采用大型沉井装配化建 造技术，在预制厂内将隔墙分块预制成半成品，现场逐块组拼成形，提升工业化建造水平。 目前，大桥两岸沉井均已启动下沉，南岸锚碇沉井下沉深度已达15.8米，计划年底全部完 工。 据介绍，汉南长江大桥及接线工程预计2027年建成通车，将打通武汉都市圈环线高速， 串起武汉、孝感、咸宁、鄂州、黄冈等城市，打造一小时通勤圈，推动武汉都市圈同城化进 程。 锚碇是一座大桥的"基石"，也是"定海神针"，由沉井和锚体组成，承担着固定桥梁缆索 的巨大拉力，沉井内有36个孔，结构类似方形蜂窝煤。 目前，武汉在建的第12 ...
